Compatible solutes

In this article, we explore the operation of the LEACH (Low Energy Adaptive Clustering Hierarchy) protocol - a protocol compatible with low-energy sources and propose a solution to improve efficiency in wireless sensor networks. The simulation results show that our solution is better in terms of the number of packets reaching the base station and the average lifetime of the sensor nodes.

In this work, the protective effect of ectoines against pH stress and high temperature has been investigated using an alkaline active xylanase from Bacillus halodurans as a model. The disaccharide, trehalose—a well-known stabiliser for biomolecules (Kaushik and Bhat 2003), has also been included in the study. The enzyme was selected as a model because it is efficiently active at high pH and is highly stable in the pH range of 5.5–10.5 at 50 °C.

Investigations of protein–solute interactions typically show that osmolytes favor native conformations. In this study, the effects of representative compatible and counteracting osmolytes on the reactivationof lactate dehydrogenase from two different conformational states were explored. Contrary to expectations, proline and trimethylamine oxide inhibited both the initial time course and the extent of reactivation of lactate dehydrogenase from bovine heart following dena-turation in guanidine hydrochloride, as well as following inactivation at pH 2.3.

Heteronuclear NMR relaxation measurements and hydro-gen exchange data have been used to characterize protein dynamics in the presence or absence of stabilizing solutes from hyperthermophiles. Rubredoxin from Desulfovibrio gigaswas selected as a model protein and the effect of diglycerol phosphate on its dynamic behaviour was studied. The presence of 100 mMdiglycerol phosphate induces a fourfold increase in the half-life for thermal denaturation ofD.

Larvae of an anhydrobiotic insect,Polypedilum vanderplanki, accumulate very large amounts of trehalose as a compatible solute on desiccation, but the molecular mechanisms underlying this accumulation are unclear. We therefore isolated the genes coding for trehalose metabolism enzymes, i.e.

Memcachedb is a distributed key-value storage system designed for persistent. A complete memcached, but *NOT* a cache solution: Memcached is good enough for cache. *NO* expiration: For memcache protocol compatible, still reserved, but we do nothing. Totally for persistent: Transaction, replication, we do our best to achieve persistent.
